Ordered a New engine for my Cushman truckster. While transferring parts from my old engine I found old o-rings inside my NEW engine. I called the company and they said "it's a used crankcase, but everything else is NEW. I made the mistake of finishing installing the engine. It hemorrhages oil right through the seam in the "new" engine. I asked for them to send a new engine, which they refused to do. They offered to review my engine for warranty, after I removed the, flywheel, shrouds, alternator, hydraulic pump, engine fan, pushrods, valve rockers, valve covers, distributor, etc. and ship it back to them.
